This invention has to do with vertically slidable sash, and is particularly concerned with that type of vertically slidable sash which is closed when in its lowermost position and opens by raising, which type is the one commonly used in the window openings ot railway cars and motor busses.

The principal object ot the invention is to provide improved means for raising and lowering a sash of the type described, which means includes a novel Connection between the sash and the actuating mechanism which is hidden from view in all positions ot the sash, does not in any way impair the weatherproofing of the sash or the frame, is inexpensive to manufacture, is easy to install and may be readily detachedl from the sash to permit removal of the latter.

Other objects and advantages of the invention will be apparent upon a full understanding of the construction, arrangement and operation of the connecting means.

One form of the invention is presented herein for the purpose or' exempliication, but it will o1"- course be appreciated that the invention may be embodied in other struc- 'turally modified forms coming equally within the scope the appended claims.

In the accompanying drawings:

Fig. 1 is an inside view of a double window equipped with the sash connection of the invention;

Fig. 2 is a vertical section through one of the window frames shown in Fig. 1;

, Fig. 3 is a. fragmentary horizontal section,

taken on the line 3-3 et Fig, 2;

Fig. l is a fragmentary vertical section, taken on approximately the line l-el of Fig. 2;

Fig. 5 is a fragmentary horizontal section, taken on the line 5-5 of Fig. 2; and

Fig. 6 is a fragmentary vertical section, taken on the line 6-6 ciI2 Fig. 2.

In the particular embodiment of the invention which is shown in the drawings, a vertically slidable sash 10 is positioned in a window frame 11. -The sash, when in its lowermost position, completely closes the opening in the frame. The stiles of the sash are arranged in guide grooves 12 which are formed in post plates 13 attached to the op- 1930. serial No. 461,895.`

posite sides of the frame. The portions of the post plates immediately Vbehind the grooves are spaced alittle from the sides of the frame, whereby to provide closed conduits 14 in which two vertical rods 15 are housed.

The lower ends of the rods 15 are rigidly secured to the ends of a horizontal cross bar 16 which is located in a deep pocket 17 beneath the sill 18 of the fra1ne,while the upper ends of the rods carry studs 19 which proe0 ject laterally through vertical slots 2O in the backs of the grooves 12 into sockets 21 in. the edges of the stiles of the sash.

The lower ends of the slots 20 in the post ii f plates are located some distance above the sill 18, preferably above the center of the sash when thelatter is closed, in order that, when the sash is raised as far asit is intended to go, the edges of the stiles of the sash will still completely cover up the slots. It will of course be understood that the length of the slots 20, as well as the clearance in the pocket 17 above the cross bar 16, is suiiicient to permit the sash to be raised to its open position. The portions of the rods 15 which 75 extend below the sill 18 travel up and down in grooved guide strips 22 which are attached to the frame work present at the sides of the pocket 17.

The studs 19 are normally maintained in the sockets 21 by means of antifriction rollers 23 which bear against theA sides of the frame 11 and are connected to the upper ends of the rods k15 by spring strips 24. The studs 19 may be withdrawn from interlocking engagement with the sockets 21 by forcing the upper ends of the rods 15 away from the stiles of the sash against the yielding resistance oii'ered by the strips 24. This may' be conveniently done, after removing certain retaining strips 2,5 and 26 detachably secured to the post plates, by inserting apointed tool of some kind in small openings 27 in the post plates at one side ot the sash and pressing back the lower laterally extending portions 28 of L-shaped spring strips 29 attached to the post plates. The portions 28 of the strips 29 are normally disposed against vthe inside faces of the post plates between the latter' and the rods 15, with the result that, when the portions 28 are forced away from the post plates, they will engage with the rods 15 and will move the latter far enough toward the sides of the frame to disengage the studs 19 from the sockets 21, whereupon the sash may be removed.

The 'cross bar 16 may he raised and lowered by'any suitable means, such as a rack 30 which is attached to the cross bar and meshes with a Apinion 31. The Vpinion 31 is journaled in the frame beneath the sill and is rotated by means of a small crank-shaped handle 32. When a pinion and rack arrangement isused, the rack may be jointed in order to fold up into an out-of-the-way position when the sash is raised, and the pinion may be urged to rotate in one direction by a coil spring in order to Vcounterbalance the weight of the sash when the latter is raised. The pinion and rack arrangement above described. which is Va well known construction, is merely shown by Way of illustration. since it will be obvious that the rods may be raised or lowered by -means yot many other different instrumentalities without departingr from the spirit of theVin-vention.

I claim:

1. In sash construction, a frame. two hollow sash guides attached to the sides of the frame, a sash mounted in the `guides tor vertical movement, .two vertical rods positioned in the hollow portions of the guides` eonnections between the rods an d the sash passing through vertical slots in the upper por- -tions'on'lyof the guides, and means for raising and .lowering the rods.

2. In sash construction, a frame. two hollow sash guides attached to the sides of the frame. a sash mounted in the fluides for vertical movement, two vertical rods positioned inthe hollow portions of the lfroides. connections between the upper ends of the rods and thesash passing through vertical slots in the upper portions only of the guides. and means for raising and lowering the rods.

3. In sash-construction, a frame. two hollow sash guides attached to the sides ot the frame` a sash mounted in the guides for vertical movement. two vertical rods positioned in the hollow portions oi the -fluides. connections between the upper ends ot the rods and thefsash passing through vertical slots in the upper portions of theguidcs. means for releasing said connections to permit removal of the sash :from thelguides` and means for raising and lowering the rods.

' 4. In sash construction@ a frame. two holllow sash guides attached to the sides ot the frame. a. sash mounted in the guides for ver tical movement. two vertical rods positioned in the hollow portions ot the guides. studs projeetiner laterally from the upper ends of the rods through vertical slots in the guides into sockets formed in the stiles of the sash, 65 and means for raising and lowering the rods.
